Massive SQL Injection Attack Compromises 380K URLs 117

Posted by CmdrTaco from the that's-a-lot-of-compromise dept.
Orome1 writes "A massive SQL injection attack campaign has been spotted by Websense researchers, and the number of unique URLs affected by it has risen from 28,000 when first detected yesterday, to 380,000 when the researchers last checked. The injected script redirects users that have landed on the various infected pages to the domain in the script, which then redirects them further to a website simulating an anti-malware check and peddling a rogue AV solution."

      Looking through the first several pages from Google, searching for the same string that was in the article, it's predominantly ASP/ASPX/CFM that is coming up. Probably nothing new, just taking raw user input and querying directly with that.

      Neither article says ... so I guess the only way to find out is to hit the internet and find out for ourselves!

    • The article didn't really say. I went looking for the same information. All i found was a lot of talk about what you will find on an infected site. The takeaway seems to be: If your site is serving up weird links that you didn't put there, sanitize everything.

      that hardly seems like news.
    • After a cursory glance at the search results of infected pages, I saw the following file types:
      Microsoft Active Server Pages (.asp)
      Microsoft ASP.NET (.aspx)
      Java Server Pages (.jsp)
      Cold Fusion (.cfm)

      Seems mostly aimed towards .asp and .aspx pages, but I would venture to guess that any web app that doesn't scrub the form input data would be vulnerable.

      • Not sure about the others, but in case of ColdFusion it's pure laziness, since there are tons of built-in features to prevent SQL injection. No additional and/or custom stuff necessary.

        • Same with ASP.NET, parametrized SQL queries are built into the ADO.NET model. Of course, some dumbass developer could be concatenating a SQL command using the raw input data without scrubbing it and running the command against the DB. Old school Active Server Pages have no such feature and any data-scrubbing had to be done in a separate function.

            This happens all the time. Developers need to be aware of SQL Injection and how to prevent it. You cannot just implement something like parameterized queries and assume that you're defended against the ignorance of other developers on your team. You have to train them.

            • It isn't always easy to get budget for training or even time for proper coding practices. Companies, especially those that use technology but are not in the technology business, want fast results and they want them on the cheap. Many business people don't understand the value prevention until they are forced to shell out for a pound of cure.
        • I use ASP.NET and for years I use parameters to fetch data from databases. Thus, specified values are searched in specific fields. I thought SQL injections were only possible thru user input from form fields and could only access databases. I don't understand how sites could be corrupted this way in order to redirect an URL.

      However, other than the article text, I can't see any evidence of a SQL injection attack, which is a different kettle of fish than XSS.

      The researchers also noted that some iTunes URLs have been injected with the script, but that Apple has done a good job in securing the site against this kind of attacks.

      "The way iTunes works is that it downloads RSS/XML feeds from the publisher to update the podcast and list of available episodes. We believe that these RSS/XML feeds have been compromised with the injected code. The good thing is that iTunes encodes the script tags, which means that the script doesn't execute on the user's computer," they explained.
